Streams and Rivers

Question 9 • IC Environmental Science - Deering

How has the removal of wetlands impacted rivers and streams?

Answer
A
It has increased the rate of absorption, causing a decrease in water levels.
B
It has decreased the rate of absorption, causing greater incidents of flooding.
C
It has hindered the migration of fish, causing a loss in biodiversity.
D
Wetland removal has had no measurable impact on rivers and streams.

Explanation

Wetlands absorb and store rainwater, slowing its movement into rivers and streams. Removing wetlands reduces this absorption, so more water runs off quickly into waterways and flooding becomes more likely. Therefore, the correct choice is “it has decreased the rate of absorption, causing greater incidents of flooding.”
